Biography

I am a postdoctoral researcher at the 51cg, specialising in assessing ecosystem health through the use of ecosystem sentinels. With a background in marine biology and ecotoxicology, my research focuses on what we can learn about the oceans from stranded marine mammals. Before joining the 51cg, I obtained her PhD from the University of Heidelberg (Germany), with my thesis assessing the suitability of the zebrafish (Danio rerio) embryo as a model organism for developmental teratogenicity.

Research Overview

Broadly speaking, my research focusses on understanding anthropogenic impacts on our planet, as we face a triple planetary crisis - climate change, biodversity loss, and environmental pollution. Every project I am involved with, I approach from the 'One Health' perspective, wherein environmental, human, and animal health are inherently linked.

Research Specialisms

  • Behavioural Biology
  • Ecotoxicology
  • Environmental Risk
  • Marine Sciences

Our research specialisms are based on the Higher Education Classification of Subjects (HECoS) which is , published under the licence.

Current Research

I am currently involved in theproject, aiming to assess the value of marine artificial strucutures within broader environmental, social, and economic contexts. This includes extensive strakeholder engagement activities, an integrated natural capital framework, novel ecosystem modelling approaches, field and laboratory studies, as well as the development of a decision support tool.

I am also part of the INSITE-funded project , where we are focussing on the breakdown and dispersal of physical particles from offshore pipelines and the mobilisation and environmental fate of contaminants found within the pipeline scale.

  • NDRI funded project '' (2021-2022): A desktop study focussing in contaminants associated with the offshore infrastructure and by-products.
  • EU Horizon project (EU-ToxRisk) 'Mechanism-based Toxicity Testing and Risk Assessment for the 21st century' (2017-2021): Driving the paradigm shift in toxicological testing away from ‘black box’ animal testing towards a toxicological assessment based on human cell responses and a comprehensive mechanistic understanding of cause-consequence relationships of chemical adverse effects.

Knowledge Exchange

I am a STEM ambassador since 2021, supporting students and showcasing the wonders of STEM research. I also volunteer for the German marine protection organisation since 2018, where I assist with insights into scientific findings, translating German texts into English, and participating in events and public engagement.
